爆炸功能对我无效？

Question

我想在使用foreach（）后将字符串更改为数组（012） 它是如何完成的？

$g = ""; 
$changer = explode(",", $g); 
foreach ($y as $key => $c) { 
    foreach ($c['movie'] as $rr) { 
     $g .= $rr->movieName . ","; 
    } 
} 

Answer 1

根据您的回答，那里有更简单的方法来做到这一点比你在做什么：

foreach ($y as $key => $c) { 
    foreach ($c['movie'] as $rr) { 
     $changer[] = $rr->movieName; 
    } 
} 

Answer 2

，我发现自己的答案唯一的问题是我的爆炸功能的位置：

<!-- my code --> 
$g ="";   
foreach ($y as $key => $c) { 
    foreach ($c['movie'] as $rr) { 
     $g .= $rr->movieName . ","; 
    } 
} 
$changer = explode(",", $g);
